Intercom Off-Hook Signaling

Intercom Off-Hook Signaling lets you send a signal to a busy extension, then wait for a replay. The signal is
one short burst of tones, which comes over the speaker of the busy extension. In addition, the ICM key at the
busy extension flashes. The busy extension user can choose not to reply to the signal if it is inconvenient to
do so.
An extension can be programmed to send Intercom Off-Hook Signaling in one of two ways: manually or
automatically. The manual-type requires you to dial a code to send the signal, while the automatic-type sends
the signal automatically any time you call a busy extension. Intercom Off-Hook signaling cannot be sent to a
busy extension when it is using Handsfree Answerback. Single Line Telephones (SLT) can send and receive
the signals. Extensions programmed for Automatic Intercom Off-Hook Signaling cannot use the Camp-On or
Callback features.
